⚡ I build production-ready, AI-powered web applications — from model training to fully deployed web products. With 7+ years of hands-on experience across full-stack development and AI/ML engineering, I specialize in one thing most developers can't offer: the full picture. I don't just integrate an API and call it "AI" — I architect robust, scalable systems where the AI layer genuinely solves your business problem. If you need a freelancer who can handle the entire stack — AI/ML backend, REST APIs, and polished frontend — you've found your person. What I build for clients: ✅ ML model development, fine-tuning & deployment (PyTorch, TensorFlow and more) ✅ LLM API Integration. GPT, Claude, Gemini integration into existing SaaS, CRMs, ERP & Web apps ✅ RAG systems — "chat with your documents" (PDFs, databases, wikis) ✅ AI agents & autonomous workflow automation (LangChain, CrewAI, LangGraph ✅ Custom AI chatbots & LLM-powered apps (GPT, Claude, Gemini, Llama) ✅ Full stack web applications (React/Next.js + Python/FastAPI/Django) ✅ Data pipelines, annotation systems & MLOps infrastructure ✅ Cloud deployment AWS, Google Cloud, Azure, Digital and many more ⚙️ Tech Stack at a glance: → AI/ML: Python · PyTorch · TensorFlow · Scikit-learn · HuggingFace · OpenAI API · Anthropic API → LLM Frameworks: LangChain · LlamaIndex · LangGraph · CrewAI → Vector DBs: Pinecone · Weaviate · ChromaDB · FAISS → Backend: FastAPI · Django · Node.js · PostgreSQL · MongoDB → Frontend: React · Next.js · TypeScript · Tailwind CSS → Cloud/MLOps: AWS · GCP · Docker · GitHub Actions · SageMaker 💡 Why Clients Choose Me: Most ML engineers can't build a polished, deployable product. Most full-stack developers don't truly understand AI systems. I bridge both worlds — and I've done it for 7+ years. You get a developer who: → Understands your business problem first, code second → Delivers working systems, not just demos or prototypes → Communicates clearly throughout — no technical black boxes → Has seen enough projects to know what breaks in production I work with startups, SMBs, and enterprise teams across the US, UK, EU, and Middle East. Whether it's a greenfield AI product or adding intelligence to your existing platform, I bring the same rigorous engineering approach. I focus on outcomes that matter: systems that save you time, reduce costs, or generate revenue. 📩 Message me with your project details — let's build something great together. #FullStackDeveloper #MERNStack #AIDevelopment #OpenAI #AIChatbot #Automation #Microservices #AWS #ML Engineer

I am working as full-time ML engineer at META. In past I have worked in Google, Amazon, and LinkedIn, where I shipped over 100 Machine Learning projects and Generative AI models into production. Today, more than 210,000 YouTube subscribers and 100s of developers on GitHub follow my work in Machine Learning, Artificial Intelligence, Agentic AI, Deep Learning, RAG, and Gen AI. ✅ My No-Risk Guarantee (100% Money-Back): I stand behind my work with a 100% Money-Back Guarantee. If my deliverables don't meet your expectations, you won't pay a single penny. NO TERMS AND CONDITIONS. NO QUESTIONS ASKED. My Credentials & Authority: ⭐ Expert Vetted Freelancer (Ranked in the top 1% globally) 🏆 💼 Current Role: Full-time Engineer at Meta 🎯 🏛️ Past Experience: Full-time Engineer at Google, Amazon, and LinkedIn 🚀 🎓 100+ certifications in AI and Machine Learning from top institutions ✅ 🥇 Ranked Top 10 Elite AI Freelancer on multiple platforms 📈 🎥 Creator of a leading YouTube channel with 200,000+ subscribers ✨ 💻 Leads a developer community of 100s on GitHub 💻 🚀 The Value I Deliver: I specialize in helping Small to Medium Businesses and Early-Stage Startups implement the same scalable Machine Learning and Generative AI systems that top tech companies use to create big positive impact in the world.
